I am pretty new to Magento (ver 2.3.5) and have had a look online to see how I can restore a full system backup. I tried like other newcomers to restore via the admin panel - but I receive a backup restore failed message. I have a full system backup, and I can see inside the compressed tgz backup file that the code is all there, and the sql database is in the public_html/var directory.
1. What can I do to restore the backup file via the admin panel - given this failed.
Some suggest I have to set file/directory permissions. But, then they have to be set back. What is the way forward here - step by step?
2. What command line can I use to restore both the code and database. For example, if the backup name is backup.tgz, how do I restore both the code and database in one line from that compressed file. Or do I have to use 2 separate commands, 1 for code restore, and 1 for the sql file restore?
What would the command line be here?
Again, what do I have to look out for regarding file permissions, so that the command line restore will work?
I don't mind the answer being spelt out to me - as I prefer all the steps, rather than assuming I know what should be known about backups and restores and directory permissions.
